DL-6CFX-F30-3QB is a new type of tea screening equipment developed by our company, It can separate fresh leaves and finished tea in one machine. It can save money and workers. It can adjust the speed of screening and wind speed. It is a necessary good helper for tea factory!
DL-6CYQT-6105 mainly used for Oolong tea processing, drum made of bamboo, the activity of withered tea was increased by shaking, It can make tea taste more fragrant, Capacity about 32 kg per batch.
This machine is suitable for the shaping and roasting process of high-grade curly tea. Tea roasted by this machine features tight and neat strips, uniform curling, bright green color, visible white fuzz, and rich aroma—fully demonstrating the characteristics of high-quality tea. The machine's heating system offers two options: electric heating and liquefied gas heating, allowing users to choose flexibly based on their actual needs.
The Matcha ball mill is designed for post-drying grinding of agricultural products (e.g., ground tea, Chinese medicinal materials) with advantages of low-temperature grinding (5-15℃) to retain raw material color and aroma, fine fineness (500-1000 meshes), PLC-controlled easy operation, and durable structure.

This trimmer comes with an adjustable height function, enabling you to adapt to different plant heights. Its high - performance cutting system ensures efficient and clean cuts on grass, shrubs, and tea branches. With a user - friendly wheel - based design, it offers easy maneuverability, making pruning tasks a breeze. Ideal for both professional landscapers and gardening enthusiasts.
4C-60L is a handheld automatic tea plucking machine designed for tea gardens. Equipped with a 2-stroke gasoline engine and a 600mm reciprocating cutter head, it efficiently harvests tea leaves with precision. Weighing only 10-14.3kg and featuring a backpack design, it ensures flexible and lightweight operation for prolonged use.
The 0.7L fuel tank supports hours of continuous work, while the centrifugal friction clutch transmission system delivers stable power and easy maintenance. Its comb-type cutting technology separates buds and leaves accurately, minimizing damage, and the negative-pressure suction tube directly collects fresh leaves into a waist-mounted bag, integrating "picking-collection" into one process
In tea leaves, the same green leaf is processed into green tea, black tea, oolong tea, etc. by controlling biological oxidation, a process also incorrectly called fermentation.
This process is more like a series of enzymatic reactions, perhaps better known as biological oxidation. The biooxidation of tea is a series of oxidation processes of catechins that are promoted by oxidase in the cell wall after the cell wall is damaged.
In the cells of tea, catechins are present in the cell fluid, and oxidase is mainly present in the cell wall, not mainly in microorganisms, so the cell wall needs to be damaged. This also naturally explains why fermented tea needs to be kneaded. According to the degree of oxidation of polyphenols, it is also divided into full fermentation, semi-fermentation and light fermentation.
In black tea, the degree of oxidation of polyphenols is very high, which is called full fermentation; the degree of oxidation of polyphenols in oolong tea is about half, which is called semi-fermentation.
For example, in black tea processing, the purpose of fermentation is to oxidize the catechins contained in the leaves. The leaf color changes from green to copper red, resulting in the unique color of black tea. After the tea liquid cell membrane is damaged, the polyphenols, amino acids and other substances in the vacuole are gradually oxidized. At the same time, due to the oxidation of catechins, some substances in the leaves undergo chemical action, resulting in the unique color, aroma and quality of black tea.
The above is the basic meaning of fermentation in Chinese tea.
Due to the variety of tea in China, the processing techniques and production methods are rich and colorful, and the definition of quality formation is different. In the production and quality formation process of some teas, in addition to the above-mentioned fermentation in the sense of biooxidation in addition to its own enzymatic reaction, In some links, microorganisms will also participate.
For example, in addition to the enzymatic effect, microorganisms are also involved in the stacking fermentation process of cooked Pu-erh tea.
After separation and research, the main microorganisms are Aspergillus niger, Aspergillus oryzae, Aspergillus claudin, Aspergillus griseus, Rhizopus, lactic acid bacteria and yeast. Nonetheless, it is still necessary for us to clearly distinguish fermentation involving microorganisms from fermentation in the sense of biooxidation. Otherwise, the conceptual ambiguity will easily lead to misinterpretation of the mechanism of tea quality formation.
